How was Japanese housing in 1970 and how is it now?

In 1970, Japanese housing was often characterized by small, single-family homes or traditional wooden structures known as "minka," reflecting post-war economic constraints and a focus on efficiency. Homes typically featured tatami mat flooring and sliding doors, emphasizing minimalism and functionality. Today, Japanese housing has evolved significantly, with a focus on modern design, sustainable materials, and advanced technology, including smart home features. Urban areas now also face challenges related to space and density, prompting innovative solutions like micro-apartments and vertical living spaces.
